' 6 Claims.' (ores-4) This invention relates to binders of the. loose leaf type and it has particular relation to apermanent locking-device for binding bodies of loose leaf sheets.

It-has been customary in maintaining records in loose leaf binders to provide various kinds of temporary 7 locking devices to prevent accidental displacement of a body "of loose leaf record sheets or of the individual-record sheets.

As a record system progresses it is desirable at certainstages of development to preserve the records involumes ofthe loose leaf-type. On the other hand; it is often desirable to assemble permanent loose leaf blank books. Although the previously known types of'binders-whichare disassembled at will, and could be employed forthis purpose, it isapparent that the'removable character of the sheets may resultlin displacement, loss, or other inconvenience.

According to one embodiment of the invention a binder of the loose leaf type has been provided which may bebuilt up into any and'which can be permanently b size of volume ound in a very simple and efficient manner. One form of the construction embodying the invention includes binding posts upon which the record sheets are assembled, and cover sections whi together 'by' manipulating parts ch are clamped of the binding posts. Permanent securing devices may be in the form of dogs which are adapt ed to be struck with a suitable tool for engaging or" anchoring them, or inaccessible clutching mechanism may be employed in telescoping parts of cover clamping devices.

For a better understanding of reference may now be had to the the invention accompanying drawings, forming a part-of this specification,

Referringto Figs. Ito 4,,the. invention is incorporatedinaloose leaf type of binder 20' hav-- ing cover sections 22 and hingingfportions 23, and including bindingjmembers 24. A plurality of binding posts or clamping devices 26 are inserted through openings 27 in the binding members 24 and through openings28pin' a body of loose/leaf 1.")- sheets 29.' r V v I Each locking device comprises an assembling section 30having an axialopening32 therein and a head 33 at one end thereof. The loose leaf sheets .are assembledupon these sections 30 before they are permanently clamped together. Each; of these sections isadapted to receive in telescoping relationinits opening 32 a cooperating section 34in the form of 'a' pin having an axial opening 36 therein which communicates with a radially disposed slot or recess 3'? extending along one side thereof. One wall, that is, the bottom of the slot is inclined outwardly, as indicated at 38, toward one end ofthe section and'a' head 391s formed at the other end'thereof.

After the body of sheets 29 has been built up upon the sections 30 to a thickness equal-approximately to the thickness of the body of sheets 29 shown by Fig. 2, and itis desired to clamp them together permanent/13 .5 dog 40' having one side formed with teeth 42 is inserted into each of the slots. 37 in such manner that the teeth project outwardly- Then the pin section 34, together with the dog, is inserted into the opening 32 of thetubularsection 30. One sideof the dog engages the inclined wall 38 of th'e'slot and the opposite side having the. teeth 42 thereon contacts the surface of the wall defining the opening 32'. An anchoring pin 43 in the form of a nail, having'a blunt end, or the like, is then inserted l in the opening 36 and driven against the dog by means of a suitable tool thereby wedgingthe dog tightly between the wall of the opening 32' and the inclined portion 38 of the wall. Thus the teeth 42 bite'into the wall'of the opening 32. 1 Therefore, any force tendingto withdraw the section 34 from the section 30 wedges thedog progressivelytighter and the sections are thereby firmly and permanently secured together. 'The heads of the sections engage theouter surfaces of the clamping members 24 of the cover sections and accordingly the entire binder is permanently assembled in compact and neat form. The pin 43 is withdrawn and employed for locking other sections in the same manner.

In the form of the invention shown by Figs. 5 to 7 a locking device 44 which is adapted to clamp the binder in the same manner as that described with reference to Figs. lto 4 is composed. of interfitting sections 46 and 47, the latter of which is tubular in form and is provided with a head 48 at one end thereof. The other section is. provided with a head 49 at one end and includes a stem 50 screw threaded axially intothemain body portion of the section. An intermediate eylindrical portion 52 of the stem is smaller in diameter than the body portion of the section and-abuts against the end thereof. A conical surface 53 adjacent the end of the stem increases in diameter toward the end until it is almost as large as the internal diameter of "the tubular section 41 A collar 54 surrounding the intermediate portion 52 has aflared mouth surface 56 corresponding approximateiy to the configuration of theecnical surface 53 and a plurality ofballs 57 are rotatably disposed within recesses 58 .injthe collar in such relation'that' portions of the ball extend outwardly beyond the outer surface of the collar and other portions thereof extend inwardly beyond the. internal surface of the collar at-the beginning of the flared mouth surface 56. One end of a coilspring 59 that surrounds the intermediate portion 52 and isunder compression rests upon the end of the collar 54 and normally urges the balls in wedging relation between-the inner surface of the tubular section and the conical surface .53, whereas the other end of the spring rests against the end of the body portion of the section 46. From this construction it will be apparent that the section 46 can be inserted and pressed into the tubular section 47 and that the clutching of the balIs'S'Tagainst the conical surface 53 and the inner surface of the tubular section prevents disassembly of the device" 44.

Referring to Figs. 8 to 10 a clamping device .60-

is shown which comprises ajtubular section 62 having a head 63 at one end and is open at the other end to receive therein a pin section 64 having aslot 66 extending from its head 6'7 toward its other extremity. The innerwall of the pin defining the slot is curved, as indicated at 68, and'the sections 62 and 64 are assembled by telescoping them and'then inserting thes'lot 66' an elongate dog 69 having teeth or serrations 70 at one end thereof that normally face outwardly toward the inner surface of the tubular. section 63. The dog is inserted through the slot 66 which extends through the head 6'7 of the pin. 'After the binder with the loose leaf sheets therein is assembled upon the; section 62, the section 63 is inserted therein and the dog 69 is then driven inwardly until the'teeth bite into the inner surface of the section 62 as the dog rides outwardlyupon the inclined wall portion 68. '.The. .dog is driven in this manner until itsouter end is. flush. with the head. 69 of the section-63. i I 1 v Fromthe foregoing. description it will. beapparent that theseveral designsef securing devices embodying the invention are particularly adapted to be employed. in loose leaf binders to provide neat and permanent records, the. parts of which cannot be accidentally disassembledor displaced and such records are insured against undesirable tampering by irresponsible persons.
